CAR-BUNK AND LOGGING-STAKE.

Specficaton of Letters Patent.

Patented July 5, 1910.

To all whom tt may concern:

Be it known that we, OREN S. CARROLL and EUGENE S. AVEY, citizens of the United States, and residents of Elma, in the county of Chehalis and State of Washington, have invented certain new and useful Improvements in Car-Bunks and Logging-stakes, of which the following is a specification.

Our invention relates to cars used for transporting logs, and has for its object the provision of an improved Construction of bunk :t'or supporting the log having improved means for dumpng the log consisting of a vertically movable stake secured to the bunk and held in an upwardly-extended position by means of a catch secured to a shaft journaled in the bunk-frame and eX- tended transversely of the car and operated by means of an arm secured to the opposite side of the car from the movable stake, so that the stake can be lowered without endangering the operator.

Our invention will be described in detail herenafter and illustrated in the accompanying d'awings, in which- Figure 1 is a cross-section of a car-iframe showing an improved bunk in position, the' movable stake being shown in its upright position in full lines and in its lowered position in broken linos; F ig. 2, a top plan View; Fig. 3, an end view partly broken away to show the novable stake and clamping means; Fig. 4:, a view of the opposite, end of the bunk; Fig. 5, a detail View of the movable stake; and Fig. 6, a detail View of the clamping-disk to hold the stake in an upright position.

In the drawings, similar reference characters indicate corresponding parts throughout the several views.

A indicates the bed of a flat car such as is used in hauling logs.

Our improved bunk consists of an open frame l, secured to the side sills B of the car-frame by means of angular supports 2.

3 indicates a shaft journaled in supports 2 and eXtended across the car-bed A, beneath the frane l.

4 indicates a stake engaging one end of shaft 3 and having an angular extension 5 that engages a bolt 6 secured in the sides of frame 1 and held from withdrawal by means of split pin 7 or other suitable structure. The stake 4 may be removed by withdrawing bolt 6 and disengaging itfrom the shaft,

but as the stake does not lower When the bunk is in use, we shall desgnate stake t as the fixed stake, while the other stake 8 we shall designate as the movable stake. Stake 8 is 'Ormed With a transverse slot 9 in its upper end in which is mounted a crossbar 10 of an open link 11, the other end of the link being provided with a tubular cross-bar 12 to receive' bolt 13, engagng the sides of franie 1 and held in position by means of split pin 14. The lower end o' stake 8 is provided with a hook 15, and a disk 16 is journaled on the stake, having its periphery double beveled, as is shown at 17.

18 indicates a disk secured to the end of shaft 3 by means of a pin 19, seated in a slot 20 in the disk, 21 indicating a beveled lug extendng from the disk to engage the hook 15 on stake 8, and 22 indicates a projection on the disk 18, opposite to lug 21, the projection being beveled to form a groove 23 that engages the beveled periphery of disk 16 when the stake 8 is in its upright position.

24: indicates an arm secured to the other end of the shaft 3 from disk 18 by means of split pin 25 to rotate the shaft 3, said arm 24 being engaged by a staple 26 when in the position to hold the disk so that the lug 21 engages hook 15 and the disk 16 is engaged by the projection 22, and the arm may be held from accidental displacement by any suitable means, such as a padlock (not shown) engaging said staple 26.

In operation it will be understood that the movable stake 8 is lowered by rotating the shaft 3 by the operator standing at the opposite side of the car from the stake so as to be out of danger should the log roll when the stake is released. Rotation of the shaft 3 releases the clamping disk from engagement with the stake and it drops into the end of bunk-frame 1. Owing to this substantally vertical movement of the stake the log cannot jam the stake should it begin to roll as soon as the stake is lowered, but on the contrary Will assist the movement of the stake downwardly.

As the stakes 4 and 8, the clamping-disk 18 and arm 24 are secured in position by removable devices as described, it will be clear w i HaVing-thus described o-ur invention what right position, substantially as shown and described.

'2. In combination With a car-frame, a bunk supported on the frame consistng of an open frame, a shaft suitably journaled, a fixed stake removably Secured to the shaft and bunk, a movable stake having a slot in its upper end, a' link Secured to said frame and engaging said slot, and means Secured to said shaft and engaging the movable stake to hold it in an' upright position, substantially as shown and described.

, 3. In combinetion With a car-frame,

a bunk supported on the iframe and consistin i 'of an open iframe, a shaft suitably journale &fixed stake'removably Secured to the shaft and' bunk, a movable stake having a slot in fitsupper end, a link Secured to said open treme-and engaging said slo-t, a, hook on the lowerend of'sad stake, and a lug on the shaft to engage the hook and hold the stake in 'an upright position substantially as shown and described.

4. In combination With a car-frene a bunk supported on the frame and consistng of an open frame, a shaft sutably j ournaled, a fixed stake removably Secured to the bunk and shaft, a movable stake having a slot in its upper end, a link Secured to said o en frame and engaging said slot, a beveled isk journaled on said movable stake, a hook on the lower end of said stake, a disk Secured to the shaft, a lu'g on the disk to engage said hook, and grooved projecton on the disk to engage the beveled disk on the stake, an arm Secured to the shaft at the opposite end from the disk aforesaid to rotate the shaft to release the lug and p'ojection from engaging the hook and beveled disk, and means to engage the arm to hold the shaft in position to clamp the'movable stake in an upright position, substantially as shown and described.

In Witness Whereof, We have hereunto set our hands n presence of two subserhng witnesses.
